CONNECTOR FOR ANGLE-RODS.

Specification of Letters Patent.

Patented Feb. 18,1913.

Application filed May 12, 1911. Serial No. 626,669.

To all whom it may concern:

Be it known that I, EDMUND J. HILGEN- DORF, a citizen of the UnitedStates, and resident of Milwaukee, in the county of Milwaukee and Stateof Wisconsin, have invented new and useful Improvements in Gonnectorsfor Angle-Rods, of which the following is a description, reference beinghad to the accompanying drawings, which are a part of thisspecification.

This invention has for its object to provide a connecting means foranglerods, such as channel irons, T-irons and the like which arecommonly used in building construction, and comprising a sleeve of suchshape in cross section as to closely fit with the contour of the ends ofthe adjoining rods so that said ends may abut and be held firmly inalinement by means of the connector.

It has been common practice to overlap the ends of angle-rods when it isnecessary to connect them together and then the overlapping ends arebound together by means of a wire wound around them. This operationinvolves difficulties and requires considerable time and the resultingconnection is objectionable because of the necessity for the two rodsbeing out of alinement or slightly offset with relation to each other.

The object of the present invention is to overcome such object-ions byproviding a sheet metal sleeve closely fitting around the ends of therods and which may be quickly and easily placed in position by merelyslipping it over the end-of one rod and then inserting the end of theother rod therein, and in some cases tightening the sleeve around theends of the rods when they are in place.

With the above and other objects in view the invention consists in theangle-rod connectors herein claimed and all equivalents.

Referring to the accompanying drawings in which like characters ofreference indicate the same parts in the different views: Figure 1 is aside view of an angle-rod connector in place for holding together theends of channel irons; Fig. 2 is a plan view thereof with a portion ofthe sleeve broken away; Fig. 3 is a transverse sectional view thereof;Fig. 4 is a plan view of an angle-rod connector in place for holdingtogether the ends of T-irons; Fig. 5 is a transverse sectional viewthereof before the edge of the sleeve is bent to its final position;and, Fig. 6 is a similar view thereof after this operation is completed.

In these drawings 10 indicates a sleeve, preferably formed of sheetmetal bent to a tubular form having the shape in cross section of thecontour of angle-rods which it is intended to connect. Such angle-rodsmay be channel irons 11 or T-irons 12 or any other form of angle-iron,all of which are intended to be comprehended by the term angle rods asherein used, and when the sleeve is placed in position on one end ofsuch angle-rod, it forms a socket to receive and closely fit with theend of another angle rod which, when inserted therein, becomes firmlyheld in connection with the first mentionedangle-rod and in perfectalinement therewith, their two ends abutting, as shown in Fig. 2. Withthe channel iron 11 it is desirable to overlap the two edges of thesheet metal forming the'sleeve at the channel portion thereof, as shownin Fig. 3, but with the T-iron fro-m it is preferable to overlap theedges of the sheet metal forming the sleeve at the straight face of theT-iron, with the outside edge of the sheet metal left projecting beyondthe edge of the sleeve so that after the rods are placed therein, suchprojecting edge may be bent over the edge of the sleeve as shown in Fig.6 and then pressed tightly against the angle rods so as to pinch thesleeve onto the angle rods and assure a tight connection.

By the use of the sleeve connection of this invention the operation ofconnecting angle rods together is not only simplified so as to requireless time, but the work is neater and the joint is more satisfactorybecause of the rods being in direct alinement and also there is aconsiderable saving in angle iron because the rods are only required toabut each other and do not overlap for the length of the connection asbefore.

What I claim as new and desire to secure by Letters Patent is: p

1. The described combination comprising a pair of angle rods, a sheetmetal tubular sleeve conforming in shape to the contour of the anglerods, said sleeve having the ends of the angle rods fitting therein, theedges of the sheet metal forming the sleeve being overlapped with theouter edge projecting and adapted to be turned over upon the edge of thesleeve to clamp the sleeve upon the angle rods.

2. A connector for the abutting ends of angle rods comprising a sleeveof sheet metal having the same sectional shape throughout its length asthe angle rods and adapted to fit thereon so that the abutment of theangle rods is approximately midway the length of the sleeve.

3. Means for connecting and alining abutting rods of angular crosssection comprising a sleeve tubular in form and having the samesectional shape throughout its length as the sectional shape of the rodsand 10 adapted to fit upon the ends of both rods and continue a bearingengagement therewith for some distance beyond their abutment to preservetheir alinement.

In testimony whereof, I aflix my signature, in presence of twowitnesses.
